// 该文件专门用于暴露一个store对象，整个应用只有一个store对象

// 引入createStore，专门用于创建redux中最为核心的store对象,applyMiddleware执行中间间
import {createStore,applyMiddleware} from 'redux'
// 引入为count组件服务的reducer
import countReducer from './count_reducer'
//引入redux-thunk 用于支持异步action
import thunk from 'redux-thunk'
//函数柯里化
// import {composeWithDevTools} from "redux-devtools-extension";

// const middleware = composeWithDevTools(applyMiddleware(thunk))
// 暴露store
export default createStore(countReducer,applyMiddleware(thunk))
